Why is it recommended to have a remarketing list with a Smart Shopping campaign?

The correct answer is:

• A remarketing list will help Smart Shopping campaigns drive in-store only traffic based on interest in your local products.
• A remarketing list will help Smart Shopping campaigns reach users who are more likely to purchase again because they’ve already shown interest in your products.
• A remarketing list will help Smart Shopping campaigns capture keywords of users who are likely to purchase again and add the list to the campaign.
• A remarketing list will help Smart Shopping campaigns reach users who already made a purchase at a local store.
